Title: Wind mill blade
Inventor: YOSHII AKIHIKO
IPC: F03D11/00
Filed: 1990-03-20
Abstract: PURPOSE:To obtain a wind mill blade, prevented from easily causing a trouble and also easily manufactured inexpensively with no complicated device of variable pitch mechanism or the like required, by forming the blade, made into a laminated structure, partly into the laminated structure having at least one layer of asymmetrical orientation angle. CONSTITUTION:A wind mill blade 2, requiring strength, rigidity and lightness against wind force, is formed of a plurality of layers of fiber reinforced compound material. Normally the more required are the rigidity and the strength, the larger a number of layers of this fiber reinforced compound material is increased. Accordingly, normally the number of laminated layers in a base part 2a is increased larger than that in a point end part 2b, of the wind mill blade 2. A fiber orientation angle of the layer is given symmetrical orientation of + or -theta with theta=0 as the main orientation in order to increase strength and rigidity and further to ensure the symmetry of deformation. Here the point end part 2b is partly molded by laminating the layer of asymmetrical orientation. That is, of the plurality of layers of fiber reinforced compound material 2c, a single or plurality of layers of fiber reinforced compound material 2c on a surface part are formed by laminating the layer so as to provide the orientation angle thetaat 10 deg. through 50 deg. and further the asymmetrical orientation.

Abstract: PURPOSE:To remarkably reduce a time required for charging till the fully charged state is attained from the state of undetection of a reduced voltage by changing a width of a charge control pulse implementing switching control of a switching means. CONSTITUTION:When no voltage reduction detection signal is outputted from a voltage reduction detection circuit 5, a charge control circuit 6 calculates the residual charged capacity of a secondary battery 4 based on the count of a timer circuit 9.

Filed: 1985-04-03
Abstract: PURPOSE:To correct uneven wall thickness and consequently obtain a film with uniform wall thickness by a method wherein the bubble running between a die and nip rolls is rotated by means of a bubble twisting device. CONSTITUTION:Molten thermoplastic synthetic resin is extruded upwards from the slit 3 of a die 2 into a cylindrical bubble V and, after that, cooled by the cooling air jetted from an air ring 8 and pulled upwards with nip rolls 15. Because the outer peripheral surface of the upward extended bubble V is slidingly contacted with a large number of round pipes arranged on the three vertical stages of a bubble twisting device 22 rotated by a motor 3 so as to be applied with circumferential force simultaneous with the upward proceeding, a twisting force is applied to the bubble V as a whole. The resultant cylindrical bubble V is guided with a stabilizing plate 21 and folded in flat with the nip rolls 15 so as to be taken up by a take-up roller 19 in the form of a sheet-like film. Because beads developed on the peripheral surface of the bubble are dispersed in width direction after the bubble is wound on the take-up roller 19, the resultant film can be taken up in flat.
